Summary

This phase II trial studies how well F-18 fluoroethyltyrosine (fluoroethyltyrosine) works in detecting tumors in participants with intracranial tumors that have come back. FET accumulates in malignant cells within intracranial neoplasms and can be used to detect recurrent disease and characterize the grade of glial neoplasms. Imaging agents such as FET can help oncologist to see the tumor better during a positron emission tomography (PET) scan.

Conditions

  • Intracranial Neoplasm
  • Low Grade Glioma
  • Recurrent Glioblastoma
  • Recurrent World Health Organization (WHO) Grade II Glioma
  • Recurrent WHO Grade III Glioma

Interventions

DRUG

F-18 Fluoroethyltyrosine (FET)

Patients given an injected dose of 4 to 7 millicurie (mCi) of FET per scan. The radiopharmaceutical will be administered while the patient is in the PET scanner

PROCEDURE

Positron Emission Tomography (PET)

All patients receive single PET imaging lasting for 40 minutes. Acquired PET data will be reconstructed so that three time points are created: (1) Perfusion: 60-second acquisition that starts immediately when activity is noted in the field of view, (2) Equilibrium: 10-minute acquisition acquired between 10 and 20 minutes after injection, and (3) Washout: 10-minute acquisition acquired between 30 and 40 minutes after injection. A repeat PET image will be offered to adult patients.
